HOLDBACK FQR VEHICLES.

SPECIFICATION' forming part of Letters Patent No. 321,375x dated June 30,1885.

Application tiled April Q5, 1585.

To @ZZ whom, t 1yr/ay concern;

Be it known that I, EDWIN G. LYNCH, of the .fillage of Parish, in the county of Oswego and Siate of New York, a citizen of the United States, have invented certain new and useful Improvements in Holdback Attachments, of which the following is a specifica tion, reference being had to the accompanying drawings, in Which- Figure l is an elevation. Fig. 2'is a transverse section. Fig. 3 is a detail of ring. Fig. is a transverse section of the holdback without under flange.

The object of my invention is to produce a holdback scl.fhitcl1ing, selt'- adjusting, and self-relieving in its construction and opera tion.

It consists of the several devices and conibinations of devices which are hereinafter described, and are specifically set forth in the claims.

It is constructed as follows: A is the thill. B is the holdback, consisting of a tubular or slotted body, a, having a project-ing horn, b, as shown in the drawings. Upon the lower inner edge of this body b, I construct an outwardly -projecting iiange, o, in which are screw-holes. C is thetug,which passes lengthwise through the body a. D is the holdbaekstrap provided with a ring, d, upon its end, usually of rectangular form.

The holdback B is secured upon the thill by screws, so that the body lies upon and along the inner face or edge of the thill with the horn b iu front.

(N o model.)

In hitching up, I pass the tug C through the ring d and then through the holdback B, and as I draw the tug back it carries the ring back under the horn bl until the parts assume the relative positions shown in the drawings; and when strain is applied to the strap D the ring cl draws against the horn b and through that against the thill.

Vhen I unhiteh the tug from the Whittletree, I draw it out through the body (aand the tug carries with it the ring d, so that when the tug is wholly withdrawn this ring is entirely released from the horn I), and when so released the strap D and ring together act as' a lazystrap to support the tug and keep it off from the ground. In this manner the tug acts both to draw the ring into its engagement un der the horn and to disengage it.

That I claim as my invention, and desire to secure by Letters Patent, is-

1..A holdhack attachment consisting of a tubular or slotted body, n, provided with a front horn, b, constructed substantially as shown and described.

2. The combination of the holdback B, provided with horn b and thill A, with the tug C, and strap D,provided with ring Leonstrlicted and operating together, substantially as shown and described.

In Witness whereof I have hereunto set my hand this th day of April, 1885.
